LAND-ROLLER.

Specification of Letters Patent.

Patented Sept. 16, 1913.

Application filed April 16, 1913. Serial `No. 761,505.

To all whom t may concern:

Be it known that I, Mans ANDERSON, a citizen of the United States, and a resident of Hastings, in the county of' Adams and State of Nebraska, have invented certain new and useful Improvements in Land-Bolt, ers, of which the following is a specification.

My invention relates to land rollers of the type disclosed in Patent No. 904,913 to H. I. A. Anderson, the purpose of my invention being to increase the elliciency of certain annular disks shown in said patent.

In my improved constructioii, I employ a number of plain annular disks alternating with toothed disks, some of the disks being mounted upon an axle and others of the disks being journaled within the peripheral rims of the disks first mentioned and having a reasonable degree of play relatively thereto. The disks thus having play are provided with teeth which penetrate the crowns of ridges of dirt formed by the other disks thus enabling the ground te be readily cultivated and left in suitable condition to absorb moisture and also to prevent the earth from being readily washed away after being thus cultivated.

Reference is .made to the accompanying drawing in which like letters indicate like parts.

Figure 1 is a front elevation of my improved land roller complete. Fig. 2 is a vertical 'transverse section taken at a point near the middle of the roller. Fig. 3 is a longitudinal vertical section through a few of the disks showing the axle in side elevation.

The frame comprises cheek pieces 10 substantially triangular in general contour and mounted upon these cheek pieces are cross beams 11. A tongue 12 is connected with thesel cross beams and carries a standard 13 which supports the drivers seat 14. The axle is shown at 15 and is journaled in the lower portions of the cheek pieces 10. Mounted upon the axle 15 are a number of disks which, being of different character, I designate as disks of .series A and disks of series B. The disks of series B are each of a substantially annular form and the disks of this series are alternated wi-th the disks of the series A. The disks of the series A are made comparatively wide and provided with spokes 17 which radiate from hubs 16, the rim 18 being carried by the spokes. This Yrim is provided with a centrallylocated rib 19. The outer faces of the peripheral surfaces of each rim IS slope upwardly in curved lines to the apex of the ribs lf) so that when the machine is drawn along, it will form ridges in the ground. Collars 15 secured to the axle adjacent to the cheek pieces 10 hold the disks in position. llach disk of the series l carries a number of bearing lugs 2O each having substantially the form of a rib extending parallel with the axis of the disk. I preferably employ six of these lugs arranged as indicated in Fig. 3. The aggregate surfaces of the lugs, 2O together constitute a bearing surface which engages the adjacent inner surfaces of the adjacent disks so that each of the disks of the series B is virtually mounted or journaled upon the two adjacent disks upon its opposite sides. The lugs 2O do not lit within the adjacent disks but are rendered sutliciently loose to allow a reasonable amount of play preferably about one inch. Each disk of the series B is provided with a number of peripheral teeth 23.

'lhe operation of my device is as follows: The machine is drawn along the ground by horses or in any other appropriate manner and the disks of the series A by rolling upon the ground cause ridges to be formed between them. The teeth of the disks ofthe series B puncture these ridges or provide them with holes whereby they are enabled to receive moisture which is absorbed by the ground. The form thus given to the soil also prevents the lighter particles of earth from being blown or washed away.

Each toothed wheel B being loose relatively to the adjacent wheels A by dragging slightly in relation to the latter, produces a mulsh upon the top of the packed soil. The looseness of the wheel B also prevents dirt from sticking between this wheel and the adjacent wheels.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In a land roller, thc combination of a frame, an axle carried thereby, a series of plain disks revolubly supported by said axle and provided with rims and a second series of disks interposed between said first mentioned disks each of said second mentioned disks being provided with lugs which loosely engage the adjacentinner surfaces of the rims of said first mentioned disks. cach of said second mentioned disks being provided with peripheral teeth so that said rst mentioned disksform ridges in the-ground and the teeth of said second mentioned disks puncture said ridges.

provided With teeth for engaging the ground, said second mentioned disks each being further provided With bearing members loosely engaging the adj aoent inner sur- 2. In a land roller, the Combination of an 1 faces of said annulairims.

axle, a number of revoluble disks carried thereby and provided With annular rims and with surfaces for engaging the ground, and a number of other disks each located be- 10 tween two of said first mentioned disks and MADS ANDERSON.
